REVERSING MECHANISM.

Specification of Letters Patent.

Patented Feb. 16, 1909.

Application filed February 24, 1908. Serial No. 417,486.

To all whom it may concern:

Be it known that I, HENRY A. BUDDE, a citizen of the United States,residing at Hartford, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inReversing Mechanism, of which the following is a specification.

This invention relates to reversing mechanism especially adapted for usein connection with lathes and other machines, and has for its object theprovision of a countershaft mechanism of much greater compactness andmore simplified construction than has been heretofore commonly employed.

A further object of the invention is the provision of gearing and aclutch mechanism by means of which a driving pulley mounted on the sameshaft therewith may be caused to rotate in either direction or remain atrest as desired.

Other objects of the invention will be hereinafter set forth.

In the accompanying drawings, Figure 1 is a side elevation of mechanismcomprising my invention. Fig. 2 is a vertical longitudinal sectionalview thereof, parts being shown in elevation, and Fig. 3 is a transversesectional view on line 33 of Fig. 2.

Like numerals designate similar parts throughout the several views.

Referring to the drawings the numeral 3 designates a hanger frame whichis provided with bearings 4 and 5. Secured within the bearing 4 by setscrews 6 is a bushing 7 and within bearing 5 by set screws 8 is the hub9 of a casing or frame 10. J ournaled in said bushing 7 and hub 9 is ashaft 11 having mounted thereon intermediate the bearings 4 and 5 aclutch which is designated in a general way by the numeral 12, saidclutch as shown being commonly known as a friction clutch and comprisinga pair of cupshaped members 13, 13 loosely mounted upon shaft 11 oneither side of a sleeve 14, which is rigid with said shaft. Keyed on theends of sleeve 14 within members 13, 13' are friction rings 15, normallyof a diameter somewhat less than the inside diameter of said members,but adapted when expanded to become rigid therewith. The expansion ofthese rings is accomplished by means of toggle levers 16, a pair ofwhich is suitably mounted with relation to each ring. The toggle leversare actuated by wedges 17 which are located in channels 18 and securedby pins 19 to a collar 20 which is slidably mounted upon sleeve 14.Carried by a rod 21 inserted in a hollow portion of the shaft 11 is apin 22 which extends through slots 23 and 24 in shaft 11 and sleeve 14,respectively, and engages the collar 20. A similar pin 25 is carried inthe other end of rod 21 and extends through a slot 26 in shaft 11 toengage the collar 27 loosely mounted thereon. Depending from bearing 5is an angular arm 28 having pivoted in its bifurcated end 29 a lever 30by means of which collar 27 together with rod 21, collar 20, and wedges17 may be shifted to accomplish the result desired.

Rigid with the clutch member 13 is a steppulley 32 such, for instance,as may be employed for driving the similar pulley of a lathe. Secured tothe large end of said pulley by screws 33 is a flange 34 projecting fromthe hub 35 of a gear 36 which is con centric to and in the same planewith an internal gear 37, located within casing 10 and keyed at 38 tothe hub 39 of clutch member 13, said hub passing loosely through gear36. Interposed between gear 36 and internal gear 37 are a series ofidler pinions 40 mounted on studs 41 carried by casing 10. In order thatthe various parts may be assembled, it is necessary to make casing 10 intwo parts, said parts being secured together by screws 43.

Adjacent the outer end of bearing 4 and keyed to the shaft 11 is apulley 44 by means of which said shaft may be rotated at the properspeed.

In the operation of the device it is clearly apparent that,1. If theclutch actuating mechanism is in a neutral position the pulley 32 willremain at rest. 2. If clutch member 13 is made rigid with shaft 11pulley 32 will rotate therewith. 3. If clutch member 13 is made rigidwith shaft 11 the internal gear 37 will be rotated therewith, and,through the idlers 40, gear 36 together with pulley 32 will be rotatedin the opposite direction. Any suitable form of clutch may besubstituted for the one shown, also various changes in other respectsmay be made without departure from the invention and it is distinctly tobe understood that it is not limited to the exact constructionillustrated and set forth.

Havingthusdeseiibed my invention what:

I claim is,

1. The combination of a hollow powertransferring device, a clutch-devicerotative with said power-transferring device, a stationary supportindependent of and outside the power transferring device, a plurality ofgears in mesh with each other, a secon clutch-device one of the gearsbeing rotative with said power-transferring device, an other beingrotative with said second clutchdevice and the third being rotativelysup ported by said support, and a clutch-memher to alternately engagesaid clutclndevices said :clutclrinember and said clutch-devices beinginclosed by said power-transferring device.

The combination of a hollow, powertransferring device having aclosing-plate, a pair of clutchdevices inclosed by saidpower-transferring device, a train of gears, one end gear of the trainbeing rotative with one of said clutch-devices and the other beingrotative with the power-transferring device, the latter being rotativewith the other of said clutclndevioes, a boxing outside the hollow,power-transferrhig device for inclosing said train of gears and forsupporting the intermediate one thereof, and a clutch-member foralternately engaging said clutch-devices.

3. The combination of a hollow, powertransferring device having aclosing plate at one end thereof provided with an outwardly extendinghub, a pinion rotative with said hub, a clutch-device inclosed by saidpowert-ransferring device and also having an outwardly-extending hub onwhich said other hub is loosely mounted, an internal gear rotative withthe hub of said clutch-device, a

stationary boxing, a pinion rotatively supported by the boxing andmeshing with said pinion and internal gear, the boxing incl-osing thepinions and internal gear, a second clutclndeviceinclosed by thepower-trans ferring member and having an outwardly extending hub towhich said power-transferring member is keyed, a shaft extending looselythrough the clutch-devices, and a clutch-member fastened to the shaftand movable to put said clutch-devices alternately into driving relationwith said shaft. In testimony whereof I afiix my signature in presenceof two witnesses.
